Product Description

1 circuit breaker adopts the principle of rotating arc extinguishing, using the arc current by the magnetic field force, so that the arc along a certain cross-section of high-speed rotation, due to the quality of the arc is relatively light, in the high-speed rotation, so that the arc gradually elongated and constantly in contact with the fresh SF6 gas, by the cooling and extinguished. This structure of the circuit breaker has a strong arc extinguishing capacity, long electric life, breaking small currents will not produce the phenomenon of interception, will not cause the advantages of operating overvoltage, etc., at the same time, the need for small operating power, high reliability.
2 circuit breaker using miniaturized spring actuator, with reliable action, long mechanical life, simple control and other advantages. The spring actuator can be manually and electrically stored, manually and electrically closed and closed, and has a reclosing function.
3 circuit breaker box material thickness of 3mm 304 stainless steel welded from the full airtight structure, protection level of not less than P67: box on the easy-to-observe, obvious opening and closing position indicator and energy storage status indicator, indicator and operating mechanism is reliably connected to indicate the action is reliable. The box has a handling handle to avoid pulling and pulling the outlet casing.
